Overview ¶
Package jsonpb provides functionality to marshal and unmarshal between a protocol buffer message and JSON. It follows the specification at https://developers.google.com/protocol-buffers/docs/proto3#json.
Do not rely on the default behavior of the standard encoding/json package when called on generated message types as it does not operate correctly.
Deprecated: Use the "google.golang.org/protobuf/encoding/protojson" package instead.

Functions ¶
func MarshalInto ¶
Marshals a protobuf to json using lossless any encoding
func UnmarshalInto ¶
Unmarshal unmarshals a JSON object from r into m.
func UnmarshalNext ¶
UnmarshalNext unmarshals the next JSON object from d into m.
func UnmarshalString ¶
UnmarshalString unmarshals a JSON object from s into m.
Types ¶
type AnyResolver ¶
AnyResolver takes a type URL, present in an Any message, and resolves it into an instance of the associated message.
type JSONPBMarshaler
deprecated
JSONPBMarshaler is implemented by protobuf messages that customize the way they are marshaled to JSON. Messages that implement this should also implement JSONPBUnmarshaler so that the custom format can be parsed.
The JSON marshaling must follow the proto to JSON specification:
https://developers.google.com/protocol-buffers/docs/proto3#json
Deprecated: Custom types should implement protobuf reflection instead.
type JSONPBUnmarshaler
deprecated
type JSONPBUnmarshaler interface {
UnmarshalJSONPB(*Unmarshaler, []byte) error
}
JSONPBUnmarshaler is implemented by protobuf messages that customize the way they are unmarshaled from JSON. Messages that implement this should also implement JSONPBMarshaler so that the custom format can be produced.
The JSON unmarshaling must follow the JSON to proto specification:
https://developers.google.com/protocol-buffers/docs/proto3#json
Deprecated: Custom types should implement protobuf reflection instead.
type Marshaler ¶
type Marshaler struct {
// OrigName specifies whether to use the original protobuf name for fields.
OrigName bool
// EnumsAsInts specifies whether to render enum values as integers,
// as opposed to string values.
EnumsAsInts bool
// EmitDefaults specifies whether to render fields with zero values.
EmitDefaults bool
// Indent controls whether the output is compact or not.
// If empty, the output is compact JSON. Otherwise, every JSON object
// entry and JSON array value will be on its own line.
// Each line will be preceded by repeated copies of Indent, where the
// number of copies is the current indentation depth.
Indent string
// AnyResolver is used to resolve the google.protobuf.Any well-known type.
// If unset, the global registry is used by default.
AnyResolver AnyResolver
}
Marshaler is a configurable object for marshaling protocol buffer messages to the specified JSON representation.
func (*Marshaler) MarshalToString ¶
MarshalToString serializes a protobuf message as JSON in string form.
type Unmarshaler ¶
type Unmarshaler struct {
// AllowUnknownFields specifies whether to allow messages to contain
// unknown JSON fields, as opposed to failing to unmarshal.
AllowUnknownFields bool
// AnyResolver is used to resolve the google.protobuf.Any well-known type.
// If unset, the global registry is used by default.
AnyResolver AnyResolver
}
Unmarshaler is a configurable object for converting from a JSON representation to a protocol buffer object.
func (*Unmarshaler) UnmarshalNext ¶
UnmarshalNext unmarshals the next JSON object from d into m.
func (*Unmarshaler) UnmarshalNextV2 ¶
UnmarshalNext unmarshals the next JSON object from d into m.
